Thin layer chromatography silica gel is formed through the way of the highly-purified thin layer chromatography silica gel (powder) mixed with a certain quantity of binder spray, has pure white surface of plate、level-off and well-proportioned、close. Its main ingredient is SiO2·nH2O, which has chemical stability and doesn’t react with other acid and alkali except for strong base and hydrofluoric acid. 
This product can be directly used for the quantitative analysis of many kinds of organic substances and has been universally applied in the identification of main ingredients and trace impurities from pharmaceuticals, pesticide, Chinese herb medicine, organic chemical articles as well as grains and foodstuff. High performance thin layer chromatography silica gel has even the characteristics of thin and well-proportioned particles. Compared with the general thin layer chromatography silica gel, it has better separation effect on substances.
